LEDE does anyone subscribe to this?

Danny,

I don't think it's regarded as the right solution here among the pros. It does have its application in the right room with the right speakers and there os no harm in trying. I've heard this concept used with small monitors that were against the wall. The dead end was the speaker end. The listening position was far from the back wall. It was great. Most times though you need to control reflections by making them very random. I like a room filled with lots of stuff. Shelves, bookcases, knick knacks, plants, etc. The more junk in the room the better it will sound. If you like the spartan look you will likely need to be more scientific. My opinions are based on experience with various systems in a couple of different houses always having a dedicated listening room.

Danny,

I also think that LEDE doesn't apply as well to home stereo as it does for studio use. As you mentioned in your post, LEDE was really developed for studio use where the listening is (very) near-field.
I use ASC tube traps & from what I have read & personally experienced in my listening room, the LEDE concept needs to be inverted. The original LEDE says that the speaker end is dead & the listener end is live. From my experience it is should flipped - the speaker end should be live & the listener end should be dead. THIS IS A GENERAL STATEMENT 'cuz neither end is completely live nor completely dead respectively.
What I found to work best w/ tube traps in my room is:
* directly behind speakers, directly to the side of the speakers & directly behind listener should be dead.
* 4 corners of room should be reflective 400Hz & above.
* If you have more traps then the remaining space along the walls should have varying degrees of reflection/absorption for best sound. Here the user needs to tune the trap to his/her listening preferences.
FWIW. YMMV.

LEDE fell out of favor in pro studio because engineers found that mixes did not translate well from one studio to another. If you look at the majority of pop/rock releases you'll see that they were recorded or mixed at several different studios. It is important that the work done at one studio sound substantially the same when taken to another studio. Mixes of songs done at LEDE designed studios failed this important requirement. Also remember that most pro studios use a combination of near field and flush mounted monitors.
